To all whom it may concer/ni: l ,A

Be it known tha-t I, PETER S..IIEINZ INGER, a citizen of the UnitedA States, residing at Monroe,- in the county of Snohomish and Sta-te offl/Vashington, have inventeda new and useful Improvementfin Logging VEquipments, of which the following 1s a specification.

'This inventionrelates to improvements yin logging equipment and. more.l particularly to a swivell device for connecting theinain line cable used'in high lead logging with. the haul back cable and butt lines.` ,y

It is the principal object of this inventionv to provide Aa device of the abovecharacter whereby damage, particularly lto the butt line cables due to twisting, is eliminated.

More specifically, the object of the invention resides in the provision of a main line swivel with haul back and butt line connections which will -permit the usual twisting of the main cable without causing twistingor unravelling of the log carrying butt lines. Other objects of the invention reside in the various details of construction of the parts embodied in the swivel construction and the association therewith of Va plate for the butt line connections In accomplishingthese and other objects of the invention, I have provided the improved details of construction, the preferred forms of which are shown in the accompanying drawings, wherein- Figure 1 is a diagrammatic view illustrating the use of a deviceembodied bythe present invention for connecting `the main line with butt lines and haul back cable.

Figure 2 is plan view of the swivel device. e .l

Figure 3 is a side view of the same.

Referring more in detail to the drawings, 1 and 2 designate spaced apart links, forming a part of the swivel, between which, at their outer ends, a bolt '3 is extended and which, at their inner ends, are pivotally mounted on trunnions 4l and 5 projectingfrom the opposite side of a swivel blockk 6. The links 1 and 2 are retained onthe bolt 3 by means of the bolthead and nut 7 fixed at its opposite end by a pin 8 that is extended through the nut and bolt and'` they Y Centrally the-'block ist` awithin which the shank 18 of a-platef14 is' rotatably Arnounted.,"I`he shank 'is held within the block bymeansl of a.head15 formed at itsen'd. YAt the upper rearward end of thepla-te 14 is anextension 16 having a hole 17. thereinfor receiving vthe conl necting bolt of a clevis whereby ahaul back line or cable, as .indicatedV at 18v in Figure 1, maybe attachedand at the lower .portionjof the'plate is an o-peninglforreceivinga. boltf20 vwhereby a butt line connecting plate 21 .is secured toqtheplate 14. i Theplate 21 `has a broad kflat body-portion provided at one end with arecessj22 latter is so formed thatthe plate 21'may swing pivotally on the bolt 2O between positions shown in full lines and in dotted lines 5 in Figure 3. rIn the'body of the plate, at`

opposite sides, are openings 23. and 24 for receiving clevis bolts whereby ythe clevi'sesto which the butt line cables 25 are attached may be connected to the plate.

In using the device the main line cable 26 is connected about the bolt 3, the haul back;

cable 18 is connected with the platel 14,;by means of a clevislhaving a bolt'extendefdthrough the aperture l17 and thebutt lines 25 are likewise connected by clevises, vthe bolts of which extend through the apertures tended about the logs 28. The main line is be secured to a tree as shown and' is then 'extended to the winding drum of thefengine as indicated at 30, lthen when the logsing of the main line cable can take placeA without causing turning or twisting ofthe are drawn in by the 'engine the usual twist-v butt line cables and the work is thereb'y'n'ot only greatly facilitated but damage and ex.-

,pense is avoided from unravelling or twisting together of the butt lines.

Itis readily apparent that devices of this character can be made in -various sizes according to the strength required of them and the details of constructionxofthe various parts can be changedor varied without de-. i

'partingfrom the spirit of theinvention.

Having thus described my invention, what I claim is new and desire'to secure by Letters Patent, is:

`for receiving the plate. 14 therein and the v,

l. A device of the class described, coniprising a swivel block, a pair of linlis having ends pivotally connected With'the'opposite sides of' the bloek and means for connecting their other ends With ya inain line cable, a plate having a shank sWivelly iixed in the block and having an opening in its upper portion providing connection for a haul back cable, a second platepivotally fixed to the lower portion of the first plate and havingopenings therein for receiving butt line connecting devices.

'2; A device of theclass described, coinprising a swivel block having a central opening and triinnions at its opposite sides, a pair of links having ends pivotally mounted on the tiuniiions and a bolt extended between their opposite ends for the connection there- With of a main line cable, a plate having a shankv extended swivelly through the block opening and ahead on the shank for'ietaiiiing it inthe block, said plate having an opening in its ii'p-peredge forreeeiving a lia-nl back cable connection, and a second plate fixed pivotall'y" to the lower edgeof the first plate and having openings thereink a inain line cable, aplate having a shank at one end extended swivelly through the block opening and a. head on the shank for retaining it` in the block, said plate lia-ving an extension at its upperrearward edge Vprovided-With `an opening for receiving aY haul baclrline connecting device, a second plate fixed pivotally to the lower edge of the first plate so that the plates lie in perpendicular planes and the second plate is adapted to swingpivotally in a forward or rearwardly extending direction, the second platebeiiig provided with openings at opposite sides forV receiving conneetingfdevices for butt line cables.
